My husband was on private property. He got in the car, put the car in reverse and backed up. He heard a loud pop. He put the car in drive, and his foot was still on the brake. The car began to accelerate on its own with his foot on the brake until the vehicle got up to 60 miles per hour. Trying not to hit the house, or the person outside of the property he maneuvered the car into the back yard. The car was steadily picking up speed and his foot was on the brake the entire time. He could not get the gear to shift or the brakes to work. The vehicle struck a tree and that impeded the movement of the vehicle. He turned the car off and got out of it.
